The nitrogen springs specifically designed for molds are high-pressure sealed components that undergo rigorous inspection and testing before leaving the factory, ensuring zero gas leakage.Therefore, proper installation and usage by customers are essential to guarantee their safety,reliability, and optimal service life.

1. When the dedicated nitrogen spring for molds is used as an independent component, it generally requires no disassembly or maintenance during its service life after installationin the mold.

2. When nitrogen springs are used in a system, they generally require guidance fromspecially trained personnel or professionals. Special attention must be paid to ensuring that the nitrogen within the cylinder is not fully released before any disassembly or maintenance is performed, to prevent accidental incidents.

3. The screw at the lower end of the nitrogen spring dedicated to the mold primarily serves to protect and reinforce the seal; it must not be removed or struck arbitrarily.

4. Recommended working stroke ≤ 0.9 XS (manufacturing stroke)

5. The working base contact pressed by the upper end of the piston rod should not deviate from the piston rod axis by more than 1° (i.e., it must remain perpendicular; eccentric loading is strictly prohibited)

6. The direction of motion of the working part at the upper end of the piston rod must be parallel to the direction of piston rod movement.

7.After compressing the nitrogen spring, do not allow the piston rod to return freely to its original position, as this may cause internal damage to the nitrogen spring.

8.Maintain cleanliness on the cylindrical surface of the piston rod, avoid scratches, and strictly refrain from striking the magnetic impactor.

9. It is strictly prohibited to expose nitrogen springs to direct sunlight or high-temperature environments. The maximum allowable temperature is +80°C (with exceptions for specially designed heat-resistant nitrogen springs).

10. The nitrogen springs specifically designed for molds should be stored in a dry, well ventilated environment free from corrosive gases, with proper packaging. After unpacking and installation, if the springs will not be used for an extended period, apply a protective grease coating to the surface to prevent corrosion.

Pour:

The nitrogen springs specifically designed for molds produced by our company have undergone rigorous quality inspections. Under normal and proper usage conditions,
they will remain reliable for one year or up to 1 million cycles of reciprocating motion (stroke ≤ 50 mm). The company will provide free warranty and offer lifetime
maintenance for its specialized mold nitrogen spring products.
